The Opening Credits....

Very well done!

The music is unsettling....and the images on-screen are very well chosen.
Those images start out just showing hectic everyday life, but interspersing images of subtle savagery.....first in the animal kingdom (ants overcoming their prey....wolves fighting over a piece of meat, bearing their fangs)....and then, people....first fighting civilly (like on the floor of the NY Stock Exchange)....then political unrest/uprising...and finally, the fall of law and order--chaos and collapse.

All of this imagery unfolds progressively (but quickly)....getting more and more unsettling with each few seconds, almost like a virus taking effect and gathering steam. It creates a visceral reaction, creates a stressful feeling...and sets the tone for what's to come.

Really masterfully done.
